Migrating Notifications from SCOM 2012 R2 to 2016

· 2 Comments ·

When upgrading a SCOM environment from 2012R2 (or 2012) to 2016, one of the most time demanding tasks can be replicating the notifications settings. In my case, I had to do a brand new install, and needed some way to migrate the notifications configuration from the old SCOM environment to the new. Luckily there is a pretty quick way to achieve this. Let’s begin!

Log in to the 2012R2 environment, go to the Administrations pane, and locate and export the Notifications Internal Library (Microsoft.SystemCenter.Notifications.Internal). Export this MP somewhere locally.

Open the MP/XML file with some editing tool, Notepad, Notepad++, Visual Studio, etc….

As you can see, this MP version is version 7.1.10226.0.

If you quickly hop over to the SCOM 2016 environment, and locate the same MP (same name, Microsoft.SystemCenter.Notifications.Internal), you will notice it is a different version. What we will need to do here is, update the OLD MP to a version number just slightly higher than the one in the 2016 environment.

So, in my case, I will change 7.1.10226.0 to 7.2.11719.1. Save the XML file, and copy it over to the SCOM 2016 environment.

Next we have two options:

  1. we can either import the updated MP, or,
  2. alternatively we can delete the MP from SCOM 2016 (v7.2.11719.0)

Before doing that, it is recommended to export the MP, and save it for “just in case“. In my case, I deleted the MP.

Now if you go into Notifications settings, you will see an exact copy of the configurations from your SCOM 2012R2 environment. To enable all the notifications, or disable, execute the following cmdlet in the OperationsManager console.

Get-SCOMNotificationSubscription | Enable-SCOMNotificationSubscription
Get-SCOMNotificationSubscription | Disable-SCOMNotificationSubscription

As an FYI, I forgot to disable the subscriptions beforehand. This would have been ideal to do before saving the XML file before importing into SCOM 2016. You can edit this by replacing the following text. Run a Control+H (Replace), and Replace All, Enabled=”true” to Enabled=”false”.

 

There you go! Notifications have been replaced from SCOM 2012R2 to SCOM 2016.

Monitoring Domain Controllers in SCOM 2016 – Event ID 1102

· 4 Comments ·

So  you deploy a SCOM 2016 agent to a Windows 2016 Domain Controller, only problem is, after the agent push, discovery doesn’t work. Well, the agent isn’t corrupted… Ports are open… SCOM agent is being deployed using the System Local account…  etc. etc. So, now what?

Taking a look at the Windows 2016 domain controller and its event log, the domain controller OpsMgr log is getting bombarded with Event IDs 1102….

After some investigation, seems to be this has been an issue in SCOM 2012 (and 2012R2) as well. Well, here’s the fix…

Taking a look at the HSLockdown, the Local System account is being denied access..  Browse to the following folder “%windir%\Program Files\Microsoft Monitoring Agent\Agent “and run the following command (elevated access…), “HSLockdown.exe /L“

Now that we can see the Local System account is being denied access, let’s give it access… Running the following command, “HSLockdown /A “NT AUTHORITY\SYSTEM“. Restart the SCOM Agent (net stop HealthService.exe & net start HealthService.exe) and you should be good to go now!

Cheers!
